A map of where people refer to soft drinks as Soda, Pop or Coke has been making the rounds in my office. It'll always be soda to me, despite me now living in a "pop" state: http://popvssoda.com/countystats/total-county.html
I grew up in Virginia, and when my first son was about 3 months old, I was back visiting and took my son to the grocery store. At the checkout, the cashier said, “Precious.” I said, “Thank you,” just beaming with pride at my newborn. Again, she said, “Precious,” and, again, I thanked her.
Finally, she pointed at the credit card swipe machine and said slowly, “PRESS YES.”
